I had been saving the back riveting of the rudder stiffeners for the EAA 1218 workshop just in case we needed more activities. With that behind, I decided to soldier on. Back riveting the D3 size rivets is really very easy, so I set up the bench with some carpet and the back rivet plate to try and minimize scratches to the skin. This worked our pretty well, but in one spot, the skin was right at the edge of the plate, and put a nice little dent in the skin. I was sick about it, and walked away from the back riveting the rest of the night.
I had riveted the rudder bottom halves together before the workshop, so I only had to squeeze those rivets to attach them to the right skin.
I also pop riveted the shear clips to the stiffeners, the last step before I need to mix proseal in preparation for riveting the trailing edge of the rudder. |
